Sound familiar?
The problem.
Which note even goes here?
You have a great sample, but working out its chords and bass notes by ear takes forever.
Basslines that fight the kick
The bass and the kick step on each other and the low end turns to mud.
Same boring root notes
You play the root on every beat and it never moves like the records you love.
BassSauce reads the chords for you, gives you a few choices for each change, and writes a bassline that locks to your drums, with slides, rolls and the right sound for the genre.
What it fixes
Problem in. Solved.
FIND THE NOTES
Drop a loop, LISTEN to a track in your DAW, or learn its MIDI. A / B / C choices for every chord change.
109 GENRES
GENERATE writes a bassline in the genre: 808 lines, offbeat house bass, walking neo-soul, disco octaves, dembow and more.
FOLLOW DRUMSAUCE
Uses DrumSauce's kick and 808 as the rhythm and follows every new pattern you generate there.
SLIDES + ROLLS
Click a note for a slide, right-click for a roll. SIMPLE to COMPLEX adds fifths, sevenths and approach notes.
8 SOUNDS + YOURS
808, Reese, Sub, Analog, Log Drum, Finger, Upright, or drop in your own one-shot and it plays in tune.
DRAG MIDI OR AUDIO
Edit it in the built-in piano roll, then drag the MIDI or audio straight into your DAW.
How it works
Three steps. That's it.
Made for producers who want a bassline that fits the sample and the drums, without working out the chords by ear.

Bring in the chords
Drop a loop, LISTEN to a track, or learn its MIDI.

Who made this
Built by an artist and producer.
I'm Sungwoo, an artist and producer. I've been making music for over a decade, and I build tools for the parts that slow me down.
Writing a bassline that fits a sample means figuring out the chords first, and most people get stuck right there. BassSauce does that part, then writes the bassline in the style you're making.
Drop in a loop and BassSauce finds the bass notes and writes the bassline in 109 genres: 808s, reese, walking lines. It even follows your DrumSauce kick.

Questions
Asked & answered.
Will it work in my DAW?
Yes. BassSauce ships as VST3 and AU, so it runs in Logic, Ableton, FL Studio, Studio One, Reaper, GarageBand and any DAW that loads those formats. Pro Tools (AAX) isn't supported yet.
Mac or Windows?
Both. Mac (Apple Silicon and Intel, AU + VST3) and Windows 10/11 64-bit (VST3). One purchase covers both.
Do I need to know music theory or mixing?
No. That's the whole point. Everything is built so you can get a great result fast, then tweak if you want to.
How do I install and unlock it?
Right after checkout you get an email with the download and your license key. Run the installer, put BassSauce on a software instrument (MIDI) track, click Unlock and paste your key. After that it works offline.
How many computers can I use it on?
Your key unlocks up to 3 computers.
Is it a subscription?
Never. One payment, yours to keep, with free updates.
What if it's not for me?
30-day money-back guarantee, no questions asked. Put it on a real beat, and if it doesn't earn its spot, email sungwoo@heysungwoo.com for a full refund.
Windows says "Windows protected your PC". Is it safe?
Yes. That warning shows for new apps from independent developers. Click "More info", then "Run anyway".
